A multi select DB list is stored in a sub table. It seems you have used a string to store the value but you can't. Look at the hbm of XWiki on the way the DBStringListProperty is done <joined-subclass name="com.xpn.xwiki.objects.DBStringListProperty" table="xwikilists"> <key> <column name="XWL_ID" /> <column name="XWL_NAME" /> </key> <list name="list" table="xwikilistitems" lazy="false"> <key> <column name="XWL_ID" /> <column name="XWL_NAME" /> </key> <index column="XWL_NUMBER"/> <element column="XWL_VALUE" type="string" /> </list> </joined-subclass> Now I'm not sure exactly how to do it. I've never tried it. If you make it work please tell us. 2011/11/16 Edo Beutler <[email protected]>
Hi
Today I tried to create a custom mapping for a class. One field of the class is a DBList with the "Multiple Select" option activated. To save the values to the DB I wanted to use a string field like I'm used to with static lists and non multi select DB lists. Now I get the following exception when trying to save a Document with an object attached: "java.util.ArrayList cannot be cast to java.lang.String"
How could I custom map a DBList field if String ist not possible? or is there even a simple Solution I missed?
A hint in the right direction would be appreciated Edo _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
